Can't install drivers

I can't instal display drivers on my Acer Aspire 5110 (5112), becouse I have lost my driver CD.
I have an ATI Mobility Radeon x1600. And Windows xp 64 bit.
I have downloaded the display drivers form the AMD/ATI website but the don't work. When I try to instal them, a window comes up and it says that I need to instal my Video driver before the Display driver. And I can't find the Video drivers anywhere on the Web.
When I open Device Manager I can't find ATI radeon x1600...There is only Standard VGA Adapter.
What should I do?

Attach the report file to a TechSpot post. When you create your TechSpot post, use the paper clip icon to attach the report. (If you don't see it among your icons, you need to click the TechSpot Go Advanced button towards bottom of window)

Well..... I'll also confirm some of the Everest Report data is odd as well (where Everest is reporting the wrong chipset. not sure i've ever seen it wrong like that before).

But forgetting that for the moment, let's do the following to find out for certain just what is or is not there (since you've already tried the driver from Acer site)

The correct device name in Device Manager comes from having the correct driver

I believe you're simply seeing VGA in DevMgr as that's the name of XP's generic driver

Since XP is not finding the correct graphics driver for the adapter, XP supplies its own default driver

Rt click on the display adapter in DevMgr, select Properties. Click Details tab. Do you see a Device Instance ID? Keep that window in view so you can refer to it in next step

Check if XP is reporting Problem Devices(and if any ID you saw step above might also occur in this step)

Click Start->Run, enter: msinfo32

Click the + sign next to Components to expand it

Click Problem Devices. Anything appear?

If yes, click on it, then Edit->Select All, Edit->Copy Paste into next post

Any problem device match the ID from step 1?

Check if Acer provided a recovery partition on your hard drive
They're typically hidden so you won't know unless we look. Do you get any response from holding down these two keys at same time? <Alt> and <F10>

Are you familiar how to get into your BIOS when you reboot? If yes (you already know how) please look through current BIOS settings to see if any option looks like the display/graphics device can be disabled/turned off. Review all the settings (don't change anything if not familiar with it.. but to take a look and report back)

In any case, i'd like to get additional info from msinfo32

Click Start->Run, enter: msinfo32

Click Components->Display

Click File->Export. Save the text file to your desktop and attach to your next post

Also, do you have an LAN connection problem? (an ethernet controller is listed in Problems devices ) or do you only use a wireless adapter maybe?
